C E Poston Inc holds Florida licence RF0046500, a RF classification which authorises work as a certified/registered plumbing contractor. An "R" prefix means the licence is registered, which limits work to the local jurisdictions that accepted it rather than the whole state.
This licence was first issued in 1984, which makes it one of the longest-held licences for the trade in this area. Roughly 1% of the 195 active plumbing licences based in the Melbourne & Space Coast area were issued earlier than this one, and the local median sits at 2016. That is 42 years of continuous licensure.
C E Poston Inc is one of 24 active plumbing licences registered to an address in Cocoa, so you have local alternatives to compare quotes against.
The licence is recorded as expiring on 08/31/2027. Florida licences renew on a fixed cycle, and a licence that is not renewed moves to delinquent status — which is why the expiry date matters if you are planning work close to that date. Confirm the current status on the state portal before signing a contract.
